A suppressor works to reduce the noise of your rifle and it is therefore important for you to find one that will work to your satisfaction.

Suppressor Legality 101

Before moving forward with your 6.8mm suppressor purchase, you need to get something important out of the way first – which is the legality of owning and using a suppressor. For the moment, the usage of suppressors is legal in 42 states across the US.

Even if the state is on the list, we would advise you to check to see if any local ordinances pertain to purchasing, owning, or using a suppressor. It’s always better for you to double-check and verify than to buy a suppressor and end up with legal trouble.

One example is that although California is one of the eight states excluded from the list, you may still be allowed to purchase, own, or use a silencer if you possess a valid FFL. So, do be sure to do your due diligence before purchasing.

Aspects to Consider when Choosing Suppressors

When choosing which suppressors to include in our list, we rate them based on a few factors that stuck out as unique. Nonetheless, it is still important for you to consider these aspects while shopping for a 6.8 SPC suppressor of your own:


As always, the very first thing to consider in a good quality suppressor is it’s material. Fortunately, most suppressors will be made from high-quality metals to ensure maximum durability and longevity. Since your suppressor will be handling hundreds of rounds over a period of time, durability will be a very important factor to consider. A cheap suppressor may be easy on the wallet but will sustain damage after a few rounds.

Noise Reduction

Obviously, the main purpose of a suppressor is to reduce the noise of your rifle considerably. Hence, it is important for you to find a suppressor that will be able to bring your gunshot noises down to a safe level. The magic number to look for in terms of noise is 140 decibels. The number or less than that will allow you to safely fire the AR-15 rifle without the use of ear protection.


A great suppressor doesn’t always have to be a challenge when it comes to attaching or installing it on your rifle. That’s why the suppressors you choose should be easy to install. Some suppressors may require simple tools such as flat wrenches for you to tighten the bolts and secure the suppressor in place prior to firing your weapon. This will ensure that it is secure and does not wiggle in the slightest.
